UNITED 'A s'rA WILLIAM FERGUSON, OIFJNT, MICHIGAN DoLLY Application ledkay 4,

This invention relates to tools to be used for metal bumping work, andmore particularly yto a dolly -dentations in cowls and other portions ofif an automobile due to collisions and accidents,

and the invention has for its object to provide a bumping-out tool ordolly adapted for use 1n reaching various more or less inaccessibleportions of an automobile, such for example as the indentation of thecowl without the 'necessity of tearing' down the instrument panelto getto the indentation for the'purpose of bumping it out.

A. further object of vide a bumping-out tool consisting of a shankportion adapted to be held in the hand during the bumping out operationand an arm portion provided with abumping surface having approximatelythe same curvature as the work to be bumped out, the arrangement held inthe hand to support the curved bumping outsurface agalnst the cowl orother curved surface of an automobile during the buplping out operation.

1th the foregoing and other Vobjects in view the invention consists ofthe novel conf parts as hereinafter more speci scribed, and illustratedstruction, combination and arraniglement of drawings, wherein is shownan embodiment l that changes,

of the invention, but it is to be understood variations andmodifications can beresorted to which fall within the scope In the,drawings wherein like reference characters denote corresponding partsthroughout the several views Figure 1 is a side elevation of a cowldolly in accordance with this invention.

Figure 4 is a section on line 4-4 of Figure 1.

veniently held in thejhand and which in the construction shown iscylindrical in cross sec-l or use `in bumping out 1nthe invention is toprosuch that the tool can be conveniently cally dein the accompanying.

tion and the shank is formed at one end with a tapered extension 2disposed in the same plane as that of the handle.

The extension 2 is formed with our side faces, 4, 5 and 6. Then faces 3,4 are op- 55 I posite each other. The faces 5, 6 are opiosite eachother. Each of the faces 5, 6 gra ually decreases in width from theinner to the outer end thereof. The face 3 extendsat'an inwardinclination throughout from' its inner o0 to itscuter end. The face 4extends at an -inwardinclination throughout from its inner to its outerend and at an op osite inclination with respect to face 3 where y saidfaces 314 pro-j ect from their inner ends towards the v longitudinal"axis of the shank. The face 4 is of greater-length than "face 3 andisupon a convex curve lengthwise from its inner towards its outer end.-In4 txiiansverse' section,

at any point throughout the Lface 4 is of arcu- 70 ate contour, and withsuchfcurvature being convex. The faces 5, 6 are rounded.

Formed integral with the outer end oi the I' l extension 2 is anoutwardl inclined, laterally extending anvil or arm i consisting of an'I5 inner ared portion 8 and an outer, substantially oval-shaped portion9. The outer face of the arm 7 transversely thereof-is of arcuate formproviding a continuation of the arcuate face 4 of the 'extension 2. Withreso `spect to the face 4 of the extension 2 and outerA faceof the arm7, both beingA of arcuate cn'"v tour transversely, the arc from theinner `of the'sad face'4 to the outer end ofthe arm" L j 7 graduallydecreases., .arm 7 is of greater widthA than portion 8. The arm 7 is ofless thickness-than the shank andextension.

The shankl -is of suitable length to facili-l tate holding the dolly inengagement with the work, the construction bemg such that the shank 1 isheld rmly in the'hand with the curved outer surface 4.0i the laterallyextending arm in engagement with the inner curved surface'of the cowl orother sheet metal struc- 95 ture to be bumped out. The construction ofthe outer end ortion of the arm 'I whereby its curved`sur ace isdisposed at an acute angle to the shank 1 and has its width lincreasedas at- 9 facilitates the insertion of this portion 190 The portion 9 ofthe 85 .i

of the tool into corners and other restricted places in engagement withthe surface to be one of said faces inclining. towards the other ,andof' arcuate contour transversely, and a laterall projecting, outwardlinclined arm integra with the outer end o the extension and having itsouter face of arcuate contour transversely and forming a continuation ofthe arcuate face of the extension. v
